[SOLVED] After a shutdown, computer always boots to BIOS before launching Windows ?

[joeeagle]

I've been struggling with this for a while now...

My computer has an ASUS B360 TUF GAMING PLUS motherboard and I am running Windows off of an NVMe SSD. With the exception of rare one-off cases when testing numerous solutions I have found online, every time I turn on my computer, it makes me save and exit BIOS before launching Windows.

I have tried almost all of the different boot settings in BIOS, disabling fast boot, etc. and I have tried using a different NVMe slot and disconnecting my hard drive (used for games), but nothing has worked.

Latest version of BIOS and chipset are installed.

Other PC specs:
i5 8600k
GTX 1060 6gb
16 gb RAM 3000 Mhz

Any suggestions would be appreciated.

Thanks.

Do you need to set the date every time or just save the BIOS config before booting Windows?

Most likely it's a dead (or dying) CMOS battery.

I tried replacing the CMOS Battery as well, to no avail.

Probably BIOS is setup to allow both boot modes (UEFI and legacy).
Wrong mode is tried first, it fails and goes back to BIOS. After you exit, the second boot mode is tried.

First determine current boot mode. You can find int with msinfo32 (BIOS mode is either Legacy or UEFI).
Disable unnecessary boot mode in BIOS. Set up boot priority properly.

After doing a bit of searching, it seems like the BIOS/motherboard is UEFI only. Windows is in UEFI mode and the motherboard BIOS is called UEFI setup utility. All the rest of the settings are currently at optimized defaults.

Windows is in UEFI mode

If you're absolutely sure about this, then go into BIOS and disable CSM.
Legacy mode will be unavailable and your pc should boot straight into windows after powering up.

CSM appears to be already disabled.
